Lignans from the bark extract of Pinus sylvestris L

Magn Reson Chem. 2006 Jun;44(6):633-6. doi: 10.1002/mrc.1780.

Abstract

Three lignans were isolated from a bioactive fraction of the 70% aqueous acetone extract of the pine (Pinus sylvestris L.) bark. Their structures were identified by high-resolution positive ion EI mass spectrometry and NMR spectroscopy. The complete assignment of proton and carbon signals was achieved by 2D NMR experiments: HSQC, HMBC, DQF-COSY and NOESY.
